Danger Will Robinson, Danger! Warning about Green House Seeds Lemon Skunk:
 
Pay close attention to your Green House Lemon Skunk to see if you get any very sativa dominant phenotypes. Green House Seeds only says medium for the height but the sativa phenotype will grow into a sequoia tree in a hurry.
 
I normally veg my plants to about 18 inches, which I did with the Lemon Skunk.
After only 17 days in flower it had hit 66 inches (5ft. 5in), that's 4 feet of growth in only 17 days and it was still going/growing strong.
For a while it averaged over 3 inches of new growth per day but then slowed down slightly to like 2.3 inches per day.
Three other strains were grown at the same time and none were even in the slightest bit stretched, in fact the Seedsman Seeds White Widow may have had the tightest nodal spacing I have ever seen and the other strains were tight too so the Lemon Skunk was not stretching due to poor/inadequate lighting since they all shared the same conditions/lighting, it was all due to it being a sativa phenotype.
 
So if early on it is obvious you have a sativa phenotype unless you have some major lighting and tons of height to grow them in throw them into flower early.
